Cell located on a property already lease to someone else

Our organization has a 99 year lease for a piece of land on a major university campus. We built a sorority house on this property in 1964. This past weekend, without any notice to our organization from the university, Verizon started installing a cell tower on the corner of our property. The lease our organization has with this university was written 52 years ago and does not address anything like a cell tower. Does the university have the right to release any part of the property they leased our origination to a new party like a cell company for another use? Also, could our organization be entitled to any of the university's cell phone tower revenues since they have impacted the looks of our property and our ability use the front yard of the property?
